Abstract: According to one embodiment of the present invention, a method by which a terminal transmits uplink data by using a preconfigured uplink resource (PUR) in a wireless communication system supporting a narrowband Internet of Things (NB-IoT) system comprises the steps of: receiving information related to the PUR for transmitting uplink data in an RRC connected state; and transmitting the uplink data by using the PUR in an RRC idle state. The information related to the PUR includes information indicating a particular carrier for monitoring a first search space related to the PUR, and when the first search space overlaps a second search space in which downlink control information (DCI) related to a particular operation is transmitted, the second search space has priority.

Abstract: A method and apparatus for performing transmission in a wireless communication system is provided. A narrowband internet-of-things (NB-IoT) user equipment (UE) transmits a physical uplink shared channel (PUSCH) to a network by using a first resource unit, and transmits an acknowledgement/non-acknowledgement (ACK/NACK) to the network by using a second resource unit. The first resource unit for PUSCH transmission consists of a first number of resource elements (REs) within a first tone in frequency domain and a first time interval in time domain. The second resource unit for ACK/NACK transmission also consists of a second number of REs within a second tone in frequency domain and a second time interval in time domain. The second number is smaller than the first number.
